The Bible says in Matthew 24:36 "No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father." That never stopped people from trying to predict when the world will end. Smithsonian has a list of ten predicted apocalypses from ancient times to 2009 (when this list was first published).

An Assyrian clay tablet dating to around 2800 B.C. bears the inscription: “Our Earth is degenerate in these later days; there are signs that the world is speedily coming to an end; bribery and corruption are common; children no longer obey their parents; every man wants to write a book and the end of the world is evidently approaching.”

The world hasn't changed much since then; everyone still wants to write a book. Link
